SNAP rAsrENER.

Application led December 10, 1923. Serial Nic. 679,690.

To aZZ whom "it may concern.; I

Beit kno-wn that I, JOHN A. MANDIs, a citiZen of vthe United States,residingrat Highland Park, in the county of Wayne 'and State ofMichigan, have invented new and useful Improvements in Snap Fasteners,

of which the following is a specification.

This invention relates to fastening devices,

and in general contemplates simplifying the construction of a device ltobe primarily used in the same capacity as the device illustrated inPatent #1,370,468, issued to me on March 1 1921. v

7,Vihile the invention comprehends the provision of a fastening deviceprimarily intended for holding a neck tie secured to thev front of ashirt, and incidentally `main'tain' the tie in proper position withrelation to the collar, the fastening device is susceptible of anunlimited number of uses, `all of which are contemplated by the claim.

The invention embodies a. two part fastener, one pant being in thenature of a headed pin, and the other part in the nature of a cap`designed to receive the shank of the pin, and including a slotted slidewhich in one position'engages the shank of Ithe pin to hold therespective parts of the device associated. Y

The nature and advantages of the .invention will lbe better understoodwhen the following detailed description is read in connection with theaccompanying drawing, the invention residing in Athe construction,combination and arrangement of parts claimed.

In the drawing forming part of-this application, like numerals ofreference indicate similar parts in rthe several views, and wherein:

Figure 1l a view showing the respective parts of the fastener separated.

Figure 2 is a View showing the parts associ-ated.

.Figure 3 is a sectional view taken on the line 3-3 of Figure 2.

Figure` 4 is a detail view of the cap member. j

Figure 5 is a detail view of the resilient member.

Figure 6 is a detail view of the slide.

Figure 7 is a detail view of the guide therefor. f

Figure 8 is a. detail view of the topy or cover for said cap.l

The fastening device essentially embodies two parts vindicated atArespe'cftively'4 I in Figure 1,the part A beingin the form of a lheadedpin, the head of whichis indicated ait-10 and theshanlV at 11d"l Theshank isv reduced as at 12 to cooperate with a. locking element to 'behereinafter described wheiehyl i theparts and B are held associated.'The underside of the, head 41Y0Y is preferably roughened j as at 13 toeffectively grip Vthe material through whichtlieshfanlrofwthfe is passedincident to its association withfthe i part B.

rlhe part vB includes a capV shaped 141, the bottoml part of which isysubstantially of conical formation formed withV adepress sion15to`receive the lower end of the shank when the parts A and B arejoined together. The cap is formed to provideV an internal shoulder 16upon which the dii'erent'meiirhers of this partl ofthe device reposes. yIn other words. l Vmalte use of a memberI 17 which is' `slotted as at18Qtodefine a resilient tongue 19, this` tongfuey having aeentral'op'eniig k2O,

and a tit'orj raisedf'portion 2l at a pintad# jacent its lfreeextremity.l Arrangedupon this resilient 'member is a disk like mem-ber'22 constituting a guide for the `slide "23.l This slide is arranged tomove overV the resilient tongue 19 which Vis allowed to Aoperate withintlie'U-shaped ntien'iloer22.- j t The slide'` being provided with arestricted slot 24@ which terminates'in an opening 25. rllhe slide orllocking element is further provided with a transverse opening 26adjacent one end thereof, which end of the slide is formed to pro-vide alinge-r engaging lip 27 arranged exteriorly of the cap 14. The opposedlongitudinal edges of the slide is formed with spaced shoulders 28 and29 respectively, and these shoulders are adapted to alternately contactlugs v30 projecting inwardly from the opposite sides of the U- slide aswill be readily understood. The j disk 31 is fitted within the capshaped member 111 and holds all of the parts in a super` imposedrelation, this dislr 31 i having a.

lshank of the pin is to be passed, and the locking element or slide 23pulled outwardly so las toposition the opening4 25 of this slide inaxial alignment with the opening 2O oit' the resilient tongue 19 andwith the opening 32 of the diskv 3l. The shank ll of the pin is thenpassed through all of these parts, and when the parts A and B' have beenthus associated, the reduced portion l2 of the shank is arranged at oneend of the slot 24 formed in the slide 23. Consequently, when the slideis pushed. inwardly' to it-s active position within the cap shapedmember 14, the opposite sidesk of the slot :24 engage the reducedport-ion 1Q of the shank and holds the parts A and B immovablyassociated. When the slide reaches the limit of its inward movement, thetransverse opening of the slide is arranged immediately above the tit orraised portion 21 of the resilient tongue and this tit or raised portionthus snaps into the transverse opening of the slide holding the latterin an active position. This construction of course, prevents casualseparation of the parts, inasmuch. as the locking slide or elementcannot be accidentally moved to an inactive position, but neverthelessthe slide can be easily pulled outwardly when it is desired to separatethe parts A. and B of the fastener. It

. might .here be stated that the fastener can be'used as a scarf orstick pin, or as a fastener for lodge emblems or the like, it is alsoparticularly useful as a separable or detachable button which can beused on garments, especially overalls or the like, so that the buttons.can be removed when it is necessary to send the garments to thelaundry. The simplicity ot the construction, plus the convenience withwhich the component parts can be assembled or disassembled arecharacteristic features of the invention, and it is 4to be furtherunderstood that it is not necessary to provide a button oit theinvention will be readily apparent', I

desire to have it understood that I do not limit myself to what isherein shown and rl described, and-that such changes may be resorted towhen desired as fall Within they scope of what is claimed.

Having thus described the invention, I claim: y

A two part fastening device, one part including a headed shank, theother part em,` bodying a cap shaped member, a disk closing one end ofthe member and having a cent-ral opening, an internal shoulder formed onsaid cap, a slide adapted to be moved inwardly and outwardly of saidcap, a` U. shaped member supported by said shoulder and constituting aguide for .said slide, cooperating means carried by the slide and saidguide 'for limiting the movements of the former, said slide having anopening` adjacent one end and adapted to coincide with the opening otsaid disk to receive the shank of the first mentioned memberwhen theslide is moved outwardly, said slide also having a longitudinal slot toreceive said shank when the slide is moved inwardly, and thus hold therespective parts of the device associated, and a member supported bysaid shoulder and including a resilient tongue operating within theU-shaped member, and cooperating means carried by said tongue and slide"for holding the latter iXed relatively to the cap shaped member whenmoved Within the latter.

In testimony whereof I afiix my signature.

JOHN A. MANDIS.
